brink of divorce with newborn

Hi everyone. I desperately need advice. I had a baby 3 months ago and my husband and I are on the brink of divorce. We believe that your spouse comes first and then your children. But Idk how to put my husband first while having a newborn. I know one day I will be able to prioritize my husband but I cannot figure out how to do that now. He is unhappy that I pour all my time into our baby. He feels like I have abandoned him. How do I put him first? I want to add I do the majority of the household chores and care for our daughter so I am left with little time and little energy.
We know divorce is not allowed in God's eyes unless there is physical abuse or adultery which is not an issue. But it feels like he will leave at any moment due to how unhappy he is.
